The Second Season of "Unforgettable" Premieres Sunday, July 28, 9:00 PM

CBS announced today summer premiere dates for two original scripted dramas, a new alternative series and an expanded season of BIG BROTHER.

A new reality competition series based on the hit UK format "The Great British Bake Off," premieres Wednesday, May 29 (8:00-9:00 PM, ET/PT). The series features skilled amateur Americans competing in baking challenges with one ultimately being crowned the winner.

UNDER THE DOME, a new 13-episode serialized drama based on Stephen King's best-selling novel and produced by Steven Spielberg's Amblin Entertainment, opens Monday, June 24 (10:00-11:00 PM, ET/PT). HAWAII FIVE-0 will move to Friday (9:00-10:00 PM, ET/PT) during the summer.

UNDER THE DOME is the story of a small town that is suddenly and inexplicably sealed off from the rest of the world by an enormous transparent dome. The town's inhabitants must deal with surviving the post-apocalyptic conditions while searching for answers to what this barrier is, where it came from and if and when it will go away.

The summer reality hit BIG BROTHER will have a longer edition this summer, premiering two weeks earlier than previous years on Wednesday, June 26 (9:00-10:00 PM, ET/PT).

BIG BROTHER will be broadcast three nights weekly - Tuesdays (9:00-10:00 PM, ET/PT, beginning July 2), the LIVE eviction show hosted by Julie Chen will be broadcast on Wednesdays (9:00-10:00 PM live ET/delayed PT, beginning July 3) and Sundays (8:00-9:00 PM, ET/PT, beginning June 30). The Wednesday live eviction show will move to 8:00-9:00 PM, ET/PT on July 17 after the reality baking series completes its season order.

UNFORGETTABLE, starring Poppy Montgomery as a police detective with a rare condition that makes her memory so flawless that everything is embedded in her mind, and Dylan Walsh as her ex-boyfriend and partner, returns for its second season on Sunday, July 28 (9:00-10:00 PM, ET/PT).
